Q. hi i had emax crowms to front 6 teeth 3 years ago in india and was very happy with the work.unfortunately the front two have fractured at the back and it feels like a slither if emax has come off the front tooth which now looks like a grey mark as the crown it see through at the bottom.cannot get to india this year would it be possible to get a good match for 2 front crowns to be replaced and if possible at what cost many thanks,
